Title: Antimicrobial agent m-259 and method of preparation
IPC: B60G17/052
Filed: 1962-06-28
Abstract: <PICT:0981278/C2/1> The invention relates to the production of antimicrobial agent M-259 by cultivating an antimicrobial agent M-259-producing strain of the organism streptomyces nigellus, e.g. S. nigellus NRRL 2920, under submerged aerobic conditions in a culture medium containing assimilable sources of carbon, organic nitrogen and inorganic salts until substantial antimicrobial activity is produced by said organism in said culture medium.  The culture medium may also contain an insoluble buffering agent and a non-toxic defoaming agent and may be maintained at a temperature from 24-32 DEG  C. for 3 to 6 days.  The antimicrobial agent M-259 is recovered from the whole broth or the culture filtrate by extraction with a water-immiscible polar organic solvent, e.g. butanol or chloroform, evaporation of the extract to small volume, addition of an inert, non-polar organic solvent, e.g. pentane or hexane, to precipitate impurities and evaporation of the clarified solution obtained.  The crude product may be purified by chromatography on activated magnesium silicate or silica gel and elution with a mixture of a hydrocarbon and a more polar solvent, e.g. methanol, ethanol or acetone, and recrystallization.  Antimicrobial agent M-259, which in its free base form crystallizes as yellow triangular prisms which melt at 155-157 DEG  C., has the following properties:-it is substantially insoluble in water; somewhat soluble in acetone, saturated hydrocarbons, benzene, ethyl acetate, butanol, ethanol and methanol, but readily soluble in dimethyl formamide, chloroform, dimethyl sulphoxide and acidified absolute ethanol; has a U.V. absorption spectrum in methanol exhibiting maxima at 235 mm  (E1%1 cm. = 480) and 335 mm (E1%1 cm. = 960); an I.R. spectrum as shown in the Figure; X-ray diffraction d-spacings in <\>rA of 10.2, 6.5, 5.7, 5.15, 4.72, 4.50, 4.20, 3.88, 3.37, 3.25, 3.04, 2.95, 2.85, 2.63, 2.56, 2.47, 2.23, 2.12, 1.97, 1.90 and 1.78; elemental analysis C = 63.00%, H = 6.43%, O = 18.42% and N = 11.95%; M. wt. = 795\sB60; and an <FORM:0981278/C2/1> (1 mg. in 1 ml. of ethanol) and is non-dialysable and gives negative results in the acrolein, ninhydrin, phosphate and biuret tests.  The antimicrobial agent M-259 may also be used as a herbicide (see Division A5).ALSO:Bactericidal and herbicidal compositions comprise Antimicrobial Agent M-259 (see Division C2) in the form of a dust, an aqueous dispersion or an emulsion.

Title: Improvements in the manufacture and production of valuable hydrocarbons from tars, mineral oils and like liquid hydrocarbon materials
IPC: C10C1/20
Filed: 1928-09-03
Abstract: 301,059. I. G. Farbenindustrie Akt.- Ges. Nov. 24, 1927, [Convention date]. Hydrogenation, destructive.-In the destructive hydrogenation of carbonaceous materials the products to be treated are passed through a series of reaction vessels, i.e. more than two, arranged one behind the other so that no appreciable cooling of the materials occurs between the vessels. Cooling is prevented by making the connections between the vessels as short as possible, by employing a high rate of flow, or by surrounding the connections with jackets containing a heating medium. By arranging the vessels in series less gas need be maintained in circulation to obtain a given speed of flow in the reaction chambers than when single vessels or vessels in parallel are used, and a single heat regenerator only is required. The initial materials may be used in the liquid or vapour state and sufficient liquid constituents are allowed to remain in the last reaction vessel to permit easy removal of the residues. Catalysts may be used either in dispersion in the treated materials or fixed in the reaction vessels. One cubic metre of brown coal tar, together with 1000 cubic metres of hydrogen (measured at atmospheric pressure) under 200 atmospheres pressure, is passed hourly through 5 reaction vessels I-V arranged in series so that one or more can be cut out for regeneration of the catalyst, the total capacity of the reaction vessels being about 1 cubic metre. The tar and hydrogen are introduced by pressure pumps A, B, and are preheated in a coil C to 410‹ C., whereupon they enter the reaction vessel I through a valve D1, and pass upwards through a fixed catalyst mass J1 consisting of molybdenum trioxide and zinc oxide. The products pass to the next vessel II through insulated pipes R1, S1 and in a similar fashion through the remaining vessels, the temperature rising in each vessel by about 5-10‹. The final products pass through a condenser M into a stripping vessel N, from which the liquid products are withdrawn through a valve P, while the gases are recirculated by a pump Q. Liquid reaction products may be removed from each vessel separately through valves G<1>-G<5>. The catalysts in the vessel I may be revivified by isolating this vessel by closing valves D1 Ll and opening valve H1, removing the contents through valve G1, and blowing in air or nitrogen through valve L1. Specifications 213,295 and 256,964 are referred to.

Title: Method of and Machine for Applying Covers to Containers
IPC: B65B7/16
Filed: 1968-05-27
Abstract: 1,194,454. Applying covers to containers. ANDERSON BROS. MFG. CO. 27 May, 1968 [21 Aug., 1967], No. 25306/68. Headings B8A and B8C. In a packaging machine for sealing a continuous cover sheet to the open tops of successive containers, uniformly spaced in a row, means are provided for ensuring that markings (e.g. label indicia) on the cover sheet register, within predetermined limits, with the container tops. When the registry strays beyond the predetermined limits, the spacing between adjacent container tops is adjusted until the desired registry is re-established, whereupon the containers are returned to their uniformly spaced condition. As shown, the invention is applied to a packaging machine, substantially similar to that described and illustrated in Specification 1,120,950. Adjacent container-carrying pockets 23 are pivotally connected by pins 28, carrying rollers 29, which run along rails 32. The distance between the centres of adjacent pockets 23 is less than the distance between the centres of adjacent label areas on the cover sheet 21, so that during normal running of the machine, the label areas begin to lag behind the containers (not shown) in the pockets. When this lag exceeds the predetermined limits, cams 42<SP>1</SP> are pivoted from the position shown in Fig. 4 to that shown in Fig. 6 so that the rollers 29 are lifted from the rails 32 to run over ramp formations of the cams. This increases the spacing of the centres of adjacent container tops beneath a rotary sealing head 50 to a value greater than that of the spacing between adjacent label areas, so that with further runnng of the machine, the registry is restored to within the predetermined limits. The cams are then returned to the position shown in Fig. 4. The sealing head 50 seals the cover sheet 21 to the longitudinal edges of the containers, sealing of the transverse edges being effected by a following rotary head 60. Movement of the cams 42<SP>1</SP> may be effected manually by means 47-49. Alternatively, means for sensing the registry of of label areas and containers and for moving the cams automatically in response to such sensed registry may be provided. Such means, Figs. 8-10 (not shown), includes a photo-cell for sensing a mark associated with each label area and switches, operated by the rollers 29, for sensing the passage of containers. These sensed operating characteristics are fed to a control circuit, which is arranged to actuate pneumatic means, for moving cams 42<SP>1</SP>.

Abstract: Glyceride oils are catalytically hydrogenated without the formation of high melting point isomers and simultaneously decolorized by treatment with hydrogen at a temperature between 100 DEG  C. and 200 DEG  C. under 1-3 atmospheres pressure, preferably at 150 DEG  C. and atmospheric pressure, in the presence of a non-colloidal particulate nickel-alumina-silica catalyst containing between 15 and 50 per cent nickel, such that the proportion by weight of nickel to oil is from 0.02-0.30 per cent. The catalyst, preferably containing 45.5 per cent nickel, 8.1 per cent alumina and 45.4 per cent silica, part of which may be in the form of diatomaceous earth, is prepared by reacting an aqueous solution of a nickel salt and an aluminium salt, preferably chlorides, with an aqueous solution of an alkali metal silicate at a temperature of at least 75 DEG  C., preferably from 80-90 DEG  C., gradually adding over at least 30 minutes and preferably less than 80 minutes, an aqueous solution of an alkali carbonate, preferably sodium bicarbonate, also at a temperature of at least 75 DEG  C.  The precipitate so formed is washed, dried, for example, at 105-110 DEG C., and pulverized to pass a 120-mesh screen and should have a bulk density of 0.10-0.25 kg./litre.  The precipitate is then reduced with hydrogen at an elevated temperature, preferably 425-550 DEG  C.  The reactants should be chosen such that the resulting catalyst has a nickel content of between 5.0 and 25.0 atom weights per formula weight of alumina and from 4-16 formula weights of alumina per 45 formula weights of silica.  The catalyst may be mixed with a protection oil such as refined bleached coconut oil while maintained in an atmosphere of hydrogen, pure carbon dioxide or inert gas to form a solids-in-oil suspension containing 35 per cent total solid and 16.3 per cent by weight of nickel.
